The answer to your question is:  Yes, I can.


You haven't asked for the trigonometric expression, but here it is anyway:

Graph the function. f(x)=2x^2-5<br> please help ill give you brainliest
snow_lady [41]

f(x)=2x^2+0x-5

Find the vertex

0/4=0=x

Input x into the equation to find y or f(x)

0+0-5=f(x)

(0,-5) = Vertex

Now find a random x coordinate to input into the equation.

Let's do 4.

32+0-5=f(x)=27

It may not look like a parabola due to it being uneven.

How can you use a rate to compare the costs of two boxes of cereal that are different sizes?
Leya [2.2K]
If you are given a unit rate (ex: $0.59 per ounce) then you can multiple this by the weight of the cereal to find the cost of the entire box. Do this for both boxes, and then compare the costs.

Hope this helps. I'm not sure that I'm on the right path, but I can help you further if you provide more details.

Good luck!
